Tag to be used with the master branch of atlas/athena. Update(s) since 2.0.147: - Updated CheckerGccPlugins with the following: * Various cleanups/fixes. Updates for gcc13. * Remove code for ctor/dtor attribute workaround that was needed for gcc versions prior to 10. * We special-case a number of methods, allowing them to be overridden with inconsistent threading attributes. This is used for things like the Gaudi initialize() and finalize() methods. Change to get this list from the configuration file rather than a hard-coded list. * Add new warning: passing a pointer member from a const member function to a non-const pointer argument. - Updated lwtnn to version 2.13; - Added Findgl2ps.cmake to AtlasLCG.
